The present disclosure relates to systems and methods for data routingmanagement. In one aspect of the disclosure, a system can be configuredto provide services, such as network-related services to a user device.It should be noted the present disclosure can be applicable in anynetwork environment employing a computing device, a server, a userdevice or other network entity that is involved in the management ofcommunication sessions between devices on a network. Those skilled inthe art will appreciate that present methods may be used in varioustypes of networks and systems that employ both digital and analogequipment. One skilled in the art will appreciate that provided hereinis a functional description and that the respective functions can beperformed by software, hardware, or a combination of software andhardware.

By implementing the disclosed systems and methods, a user device cantransmit a communication request to a first logical grouping ofcomputing devices via connecting to a single address (e.g., sharedcommon address). A communication management system and a communicationprocessing system can enable the communication request to be routed tocomputing devices available for processing the communication request. Assuch, if one computing device of the first logical grouping of computingdevices is not available to receive the communication request, thecommunication request can be transferred to another computing device inthe first logical grouping of computing devices that is available forprocessing the communication request. Alternatively, the communicationrequest can be transferred to a second logical grouping of computingdevices. In an aspect, each of the plurality of devices can bedistinguished by their respective device identifiers which can be uniqueto each computing device (e.g., MAC addresses). The disclosed systemsand methods can be used for communication requests such as internettelephone calls (e.g., VoIP), multimedia access and distribution, andmultimedia conferences and presentations. In an aspect, thecommunication request can be distributed across multiple communicationmanagement systems, while maintaining appearance of a single IP address(e.g., to the requesting device, to the communication managementsystems, to other devices in the network). The disclosed methods andsystem can enable dynamic swapping between the multiple communicationmanagement systems for routing data.

FIG. 1 is a block diagram illustrating an example system. The system canimplement a next generation cloud voice architecture 101. For example,the present methods and systems can comprise a cloud based sessioninitiation protocol (SIP) signaling architecture that will allow for thedeployment of session managers (e.g., SIP signaling servers) in a cloudcomputing environment, such as an OpenStack environment. In an aspect,the present methods and systems can be configured for geographicredundancy, cluster redundancy, global single signaling address scopes,cluster intelligence (e.g., Node Awareness), and/or the like asdescribed further herein.

In an aspect, the present methods and systems can be configured toprovide geographic redundancy. The system can be configured to supportmultiple session manager clusters 102 a,b,c (e.g., or session managerfarms) such that should an outage make the entire cluster 102 aunavailable, secondary clusters 102 b and/or tertiary clusters 102 c canprocess incoming and outgoing requests. As an example, a session managercluster can comprise one or more routers, one or more session switches,one or more session managers (e.g., communication server. SIP server),and/or the like. For example, the session manager clusters 102 a,b,c canbe configured to communicate across a network using various protocolssuch as Multiprotocol Label Switching (MPLS), Open Shortest Path First(OSPF) protocol, Internet Protocol (IP), and/or the like. For example,session manager clusters 102 a,b,c can communicate with other sessionmanager clusters 102 a,b,c over the network via MPLS, OSPF, InternetProtocol (IP), and/or the like. As described further herein, sessionmanager clusters 102 a,b,c can communicate performance metrics, hand offcall sessions, and/or perform other communication using the network.Though various protocols and values are shown in FIG. 1, it should beunderstood that the present methods and systems are not limited to suchprotocols and values but can be implemented using other protocols andvalues.

In an aspect, the present methods and systems can be configured toprovide cluster redundancy. For example, each session manager cluster102 a,b,c can be configured to share a single or multiple IP addressscopes such that devices signaling to the cluster can use only a singlesignaling IP address for communication to the cluster. The sessionmanager clusters 102 a,b,c can be configured to support healthstatistics, performance statistics, and/or utilization statistics pernode within the cluster and share this information with one or more (oreach) node within a session manager cluster. One or more (or each)session manager cluster 102 a,b,c can be configured to collect themetrics from one or more (or each) node within the session managercluster and share this aggregate information with other clusters.

In an aspect, the present methods and systems can provide globalsignaling address scopes. For example, the system can be configured withcustomer 104 a,b,c facing signaling IP addresses that are global innature. This configuration can be accomplished with border gatewayprotocol (BGP) and/or autonomous systems path (AS-Path) prependingadvertisements to customers. Each customer 104 a,b,c can be associatedwith a preferred session manager cluster 102 a to which the customerwill signal to as well as secondary session manager clusters 102 band/or tertiary session manager clusters 102 c. A customer 104 a,b,c mayhave two or more session manager clusters 102 a,b,c to which thecustomer signals to for geographic preference of call termination intothe network or termination into the network.

In an aspect, the present methods and systems can be implemented, atleast in part, at Layer 2 (e.g., the data link layer) of the OpenSystems Interconnection Reference Model (OSI model). Layer 2 options cancomprise 802.1Q VLAN tagging and Link Aggregation Control Protocol801.AX. The latter can bond a single IP address to multiple physicalinterfaces on a single system for port redundancy and increasethroughput. The system can be configured to span the LAG across multiplesystems such that each system can accept incoming IP traffic,specifically SIP traffic, on any member systems within the node sessionmanager cluster 102 a,b,c. The system can be configured to keep activeIP sessions active. Based on node performance metrics, the node handlingthe active sessions can be configured to communicate that the node cantake no more traffic or that the node desires to offload traffic toanother node. For example, the system can comprise a one or more sessionswitches (e.g., downstream switch) configured to store multiple MACaddresses in a MAC table and track active IP sessions for the MACaddresses. For example, each of the session manager clusters 102 a,b,ccan comprise a session switch. As another example, a session switch canbe utilized by multiple session manager clusters 102 a,b,c. The MACtable or tables can be configured to classify MAC address as GREEN,YELLOW, or RED or other similar classification system. For example,GREEN can designate that the device associated with a MAC address isavailable for receiving new IP sessions. YELLOW can indicate that thedevice associated with a MAC address can only pass existing sessions.RED can indicate that all sessions being handled by a device are to betransitioned to another MAC address. The designator in this case wouldbe the active node or standby node within the session manager cluster.

In an aspect, the present methods and systems can be implemented, atleast in part, at Layer 3 (e.g., network layer) and/or Layer 7 (e.g.,application layer) of the OSI model. The session switch for a sessionmanager cluster 102 a,b,c can be configured to be layer 3 and/or layer 7aware. For example, a SIP call can have multiple messages which may notbe tracked simply by a session, so when a node determines to offloadcalls, or stop receiving new calls, the session switch can be configuredto determine the call state. In an aspect, the session switch can beconfigured with layer 2 functionality and call awareness. The sessionswitch may not be an Ethernet switch but rather a server configuredserve the sessions to the session manager cluster 102 a,b,c and receivemessages from the nodes within the session manager cluster as to whichMAC addresses are identified as GREEN, YELLOW, or RED. At a minimum, thesystem can be configured to track and associate the Call ID with the MACaddress tables.

For redundancy, session switches can be deployed in pairs. In thisconfiguration, the globally advertised signaling, IP or IPs can beassigned to each session switch. The uplink can be a direct uplink to aUR which can be configured with weighted static routes. If the preferredroute interface goes down, the secondary session switch can beconfigured to receive the inbound sessions.

FIG. 2 is a block diagram illustrating example logic of a sessionswitch. It should be noted that for purposes of illustration examplevalues are shown in FIG. 2, but the present methods and systems are notlimited to these example values. At block 202, the session switch canreceive a SIP communication. The session switch can retrieve, request,lookup other otherwise determine a Call ID in a session table based onthe SIP communication. The session switch can determine if the call is anew call. If the call is not a new call, then the SIP communication canbe forwarded to a MAC address found in session table. If the call is anew call, the session switch can proceed to block 204. At block 204, thesession switch can determine to which MAC addresses the call should beforwarded.

At block 206, a green table is shown with MAC address associated with agreen status. The green table can be updated by the active sessionmanager. The session switch can choose the first MAC address in the listof the green table. If the device associated with the first MAC addresson the list is not responsive, the session switch can then try the nextMAC address and so on.

At block 208, an example session table is shown. For example the sessiontable can comprise session identifiers (ID) associated with MACaddresses. It should be noted that tabs were used to separate values forreadability purposes. Actual formatting in the session table may bedifferent.

In an aspect, the present methods and systems can be configured withcluster intelligence. Each cluster of session managers will haveknowledge of the cluster's own key performance indicators (KPIs), suchas CPU Utilization, available RAM, available disk space, total sessions,CPS, Layer 2 errors. Layer 3 errors, and/or the like. Additional metricsutilized by the present methods and systems. The session managers cancomprise a table of KPIs for each node within the session manger'scluster. The current active node can be configured to make decisions onwhich node to offload new calls to when node decides the node is nolonger available. The current active node can select a node to offloadnew calls to pre-defined preferred node or nodes, based on the mostpreferable node by evaluating each KPI table for each node, and/or othersimilar approaches. For example, this evaluation can be performed eachtime the heartbeat that carries the KPIs to each other node. Both, theactive and standby node can be configured to run the algorithm,determine the successors, and place this information in their respectivenode Performance Metric (PM) tables.

The session manager cluster can be configured to exchange heartbeatinformation (e.g., regular communication of information) with one ormore (or each) other clusters. The nodes compiling the remote and localcluster KPIs can be the active nodes and/or standby nodes. Keeping trackof cluster health across clusters enables each cluster to determine towhich cluster offloaded calls can be sent for load balancing. The KPIsused in the algorithm can be configured as percentage based metricsbased on total available resources and predefined integers for each KPI.This configuration can be utilized for inter-cluster load balancing aswell as intra-cluster load balancing.

Each node within a cluster can be configured with access to all routes,SIP manipulation rules, SDP manipulation rules, and/or the like. Thedatabase can be internal or external to the node, but it is preferredthat the database be external, but local to each cluster and be deployedin a redundant fashion.

FIG. 3 is a block diagram illustrating example logic of a sessionmanager (e.g., a node of the session manager cluster). It should benoted that for purposes of illustration example values are shown in FIG.3, but the present methods and systems are not limited to these examplevalues. At block 302, a SIP communication (e.g., call) can arrive at asession manager. The session manager can increase the current call countin a node PM table 303. The node PM table can comprise values forconcurrent calls, CSP, RAM, RAM utilization, layer 2 errors, layer 3errors, and/or the like. At block 304, the session manager can determinewhether a threshold has been met based on information stored in a nodethreshold table 305. For example, the node threshold table 305 cancomprise thresholds that correspond to values of the node PM table 302.Example thresholds can comprise concurrent calls, CSP, RAM, RAMutilization, layer 2 errors, layer 3 errors, and/or the like. At block306, SIP communication can be processed. At step 308, the session switchcan update one or more additional tables. For example, the sessionswitch can update the green table 310, yellow table 312, and/or redtable 314. For example, a MAC address can be removed from the green 310table and added to the yellow table 312.

FIG. 4 is a block diagram illustrating an example data routingmanagement system according to one or more aspects of the presentdisclosure. As an example, the system can comprise a plurality of userdevices 402 a,b,c,d, a grouping of a plurality of computing devices 404a,b,c,d, a communication processing system 403, and a communicationmanagement system 405. As an example, the plurality of computing devices404 a,b,c,d, communication processing system 403 and/or communicationmanagement system 405 can comprise the session switch, session manager,and/or the like described with FIG. 1, FIG. 2, and FIG. 3. In an aspect,the grouping of computing devices can be a logical grouping. In someimplementations the communication management system 405 and/orcommunication processing system 403 can be implemented one or more ofthe plurality of computing devices 404 a,b,c,d.

The logical grouping of computing devices 404 a,b,c,d can be connectedvia the network 406 and share one address (e.g., IP address). Forexample, the sharing of the address can be accomplished by associating(e.g., in a routing table or other database or table) each of thecomputing devices 404 a,b,c,d in the logical group of computing deviceswith the address. The sharing of the address can be accomplished by amanagement device, such as the communication management system 405configured to process communication requests associated with an addressby selectively sending requests associated with a an address to one ormore of the computing devices 404 a,b,c,d in the logical group ofcomputing devices. In another aspect, sharing the address can beaccomplished by use of labeling and/or other network routing technique.In another aspect, sharing an address can comprise appearing to sharethe same address. For example, communication messages sent to theaddress can appear e.g., from the perspective of the device sending themessage, from the perspective of the communication management system405, from the perspective of the communication processing system 403) tobe directed to the address, received and processed by a single device atthe address (e.g., though multiple different devices may receive and/orprocess messages and/or communications requests directed to the addressduring the same communication session), and/or the like. As an example,sharing an address can be achieved by border gateway protocol (BGP) andautonomous systems (AS) path. In one aspect, a logical group ofcomputing devices can share an address with one or more other logicalgroups of computing devices.

As a further example, sharing the address can be accomplished asfollows. The communication processing system 403 can be configured toreceive an inbound communication request (e.g., IP communicationrequest) from a user device 402. The communication processing system 403can then remove a header (e.g., address header, IP header) in theinbound communication request and forward a data packet in the inboundcommunication request (e.g., Ethernet packet) to an appropriate port ofa communication management system (e.g., communication management system405) according to one or more performance capabilities (e.g.,availability) of the plurality of computing devices (e.g., computingdevice 404 a) connected to the communication management system (e.g.,405).

In an aspect, each computing device of the logical grouping of computingdevices 404 a,b,c,d can be associated with a respective deviceidentifier. As an example, a device identifier can comprise anidentifier that uniquely identifies a computing device (e.g., a mediaaccess control (MAC) address).

As an example, in a telephone communication system, user devices 402,such as IP phones 402 a, personal computers (PCs) 402 b, personal dataassistants (PDAs) 402 c, and a SIP client 402 d, can be configured tocommunicate with a communication processing system 403. For example,user devices 402 a,b,c,d can transmit a communication request to thecommunication processing system 403. The communication request can bedirected to the logical grouping of computing devices according to theaddress (e.g., IP address) that the logical grouping of computingdevices share. The communication request can be transmitted via asignaling communications protocol such as session initiation protocol(SIP). Although illustrated in a cluster, user devices 402 a,b,c,d canbe mobile or stationary, and located throughout a network. The userdevices 402 a,b,c,d can comprise IP phones, PSTN phones, SIP softclients, residential voice gateways, other IP clients, such as Skype,MSN Messenger, office communicator, PDAs, VoIP enabled personalcomputers or a VoIP adapter, and the like.

In an aspect, the communication processing system 403 can serve as anedge server between user devices 402 a,b,c,d and the logical grouping ofcomputing devices 404 a,b,c,d. In an aspect, the communicationprocessing system 403 can be on the border between a communicationservice provider and its user devices (e.g., provide a user networkinterface (UNI)). In another aspect, the communication processing system403 can be on the border between two communication service providers(e.g., provide network-to-network interface (NNI)). As an example, thecommunication processing system 403 can be employed as an NNI when acommunication session requestor uses a different communication servicethan the user devices being requested for a communication session. Inanother aspect, in an IP-multimedia subsystem (IMS) network, thecommunication processing system 403 can provide call session control andborder gateway functions at UNI and NNI points. In another aspect, thecommunication processing system 403 can also be used to perform atopology-hiding function to prevent user devices or other communicationservice providers from learning details about how a network (e.g.,network 406) is configured or how communications placed through thenetwork are routed.

In an aspect, the communication processing system 403 can be associatedwith a database 414. The database 414 can comprise one or moreperformance capabilities of the logical grouping of computing devices404 a,b,c,d. For example, the database 414 can comprise a list ofcomputing devices within the network 406 available for processing thecommunication request, a list of computing devices available for routingthe communication request to a computing device available for processingthe communication request, and a list of computing devices not availablefor processing or routing the communication request.

In an aspect, the logical grouping of computing devices 404 a,b,c,d canbe configured to process and/or route a communication request receivedvia the communication processing system 403. In an aspect, the logicalgrouping of computing devices 404 a,b,c,d can comprise respectivedatabases 413 a,b,c,d. The database 413 a,b,c,d can store performancemetrics and predefined performance thresholds for the respectivecomputing devices 404 a,b,c,d. Performance metrics can be compared withthe predefined performance thresholds. When a performance threshold isexceeded, one or more performance capabilities of a computing device canbe change from one category to another category.

In an aspect, the logical grouping of computing devices 404 a,b,c,d cancomprise one or more communication protocol servers. The logicalgrouping of computing devices 404 a,b,c,d can operate as a server (aproxy server, a communication management server, an application server,etc.), a gateway node (a session border controller (SBC), a mediagateway control function ((MGCF), etc.), or a data management unit(e.g., an intelligent routing database (IRDB)). In an aspect, thelogical grouping of computing devices 404 a,b,c,d can be used toestablish mutually acceptable administrative procedures betweendifferent networks. Some example of networks and systems include apublic switched telephone network (PSTN) system, a public land mobilenetwork (PLMN) system, wireless distribution systems, wired or cabledistribution systems, coaxial cable distribution systems, ultra highfrequency (UHF) or very high frequency (VHF) radio frequency systems,satellite or other extra-terrestrial systems, cellular distributionsystems, power-line broadcast systems, fiber optic networks, and anycombinations of these systems and/or networks. Accordingly, thecomputing devices 404 a,b,c,d can comprise devices, such as protocoltranslators, impedance matching devices, rate converters, faultisolators, and/or signal translators as necessary to provide systeminteroperability.

The communication management system 405 can be configured to receive theperformance metrics of the logical grouping of computing devices 404a,b,c,d. In an aspect, the performance metrics can comprise one or moreperformance metrics for each individual computing device, statisticalperformance metrics for each individual computing device, historicalperformance metrics for each individual computing device, and/or thelike. The performance metrics can comprise performance metrics for thelogical grouping of computing devices as a whole, statisticalperformance metrics for the logical grouping of computing devices as awhole, historical performance metrics for the logical grouping ofcomputing devices as a whole, combinations thereof, and the like. As anexample, when a particular performance metric has exceeded a predefinedthreshold, a computing device (e.g., computing device 404 a) can provide(e.g., send, transmit, publish) the respective performance metric (e.g.,number of active communication requests in processing, utilizationstatus of CPU, utilization status of a RAM, error messages, etc.) andrelated data (e.g. computing device MAC address) to the communicationmanagement system 405. The communication management system 405 can thenupdate the database 414 associated with the communication processingsystem 403. For example, database 414 can be updated when a computingdevice (e.g., computing device 404 a) is moved from a list of devicesavailable for processing a communication request, to a list of devicesnot available for routing a communication request.

As an example, the communication management system 405 can receiveperformance metrics of a computing device (e.g., computing device 404 a)by a poll request. Specifically, the communication management system 405can execute a poll request to the computing device 404 a. The computingdevice 404 a can hold the request until a performance threshold has beenexceeded. When a performance metric exceeds the performance threshold,the computing device 404 a can respond to the poll request of thecommunication management system 405 by sending the performance metric ofthe computing device 404 a to the communication management system 405.

In an aspect, the logical grouping of computing devices 404 a,b,c,d canprocess a communication request from a public or private network (e.g.,network 406) and transmit the request to another public or privatenetwork, for example, a public switched telephone network (PSTN) 407.
